If you have Joom!Fish installed but you use it for everything else except items (articles), meaning you have created the multi-language content of your site by creating items per language inside the FLEXIcontent items manager then:-- disable the plugins: Search - Content (standard Joomla article search plugin) Search - Jfcontent (Joom!Fish article search translate plugin)-- and enable the FLEXIcontent standard search plugin, and inside it activate language filter

If you have a single language inside the FLEXIcontent items manager and you use joomfish to translate article (items) then do the opposite of the above.

NOTE 1: Searching works only for title and description, but v1.5.6, there is a new search view, that allows searching more fields, and displaying more fields that just title and description. NOTE 2: to display custom FLEXIcontent fields in the joomla search component (com_search) results please read this forum thread
